Tala/ZZ wlw/m mtu/00710615113 y Be ityknown that I, .(lnns'riin N, Henman, acitizen ofthe `United States,l residing at Columbus, in the countyot' Franklin and State oit' Ohio, have invented certain new and useful Improvornents in Demonntable Riins, ot which the 'following is a specitication.

The present invention is directed to iinprovenients in dernountable riins JEorniotor vehicle wheels and has for itskpriinary object` to Aprovide anarticfle-otfthis character which c anbe readilycollapsed atteciheing removed `troni the wheel 4`to permit the pneumatic tire to be easily and quickly renioved thereti'oin and alsoreadilyexpanded" for securing a replacedtire thereon.

A; further` object ot the `invention is to provide a rnn `ofsthis character so con-Y structedthat when 1n lts operative position collapsing of the parts will be positively eliminated so as to assurea rigid mountingr Ytor .the tire. i i y further objecto't the invention is to provide a riin which is extremely sirnple in construction and 4one which can be nianufactured at a very sinall cost without sacriticino` eiiciency `and durability of the rim.

.Vith these and other objects in view, as will appear as the description proceeds, the invention" consists in the novel features of' construction, combinations of elements and arrangen'ients ot parts, and hereinafter to be tully described and pointed out in the appended claims.

In the accompanying drawing:

Fio'ure l is a longitudinal sectional view4 through a portion of the rirn showing the sections in their operative positions, p

Figure 2 is an inside tace view showing the sections in their locked position,

Figure 3 is a perspective view ot' the sec* tions in their collapsed position, and

Figure t is a sectional `view on line `4L-fl oit Figure 1.

Referring to the drawingf l designates metallic resilient riin having the usual side tianges 2 and is split transversely so that the resultant ends will be normally spaced in this space are rnn sections t The sections 3 are identical in construertion and are each of less width than the width ot the rim l, but when in their operative positions' the combinedV width of the sections is equal to the width ot therirn 1 so aste completely lill the space between the ends and `term etfectfa continuation of the riln l,

`r .llhe ends oi the rnn 1 are each provided with vertical lugs and ears 41.1 and 5, respectively, andeachsection has yan ear@ which is pivotally connected with the respective cars 5 l0 which are adapted, whenthe sections are in their operative ypositions to receive the -1 Y K n i n i rugs 4 and `when thus engaged it will be obvious thatthesections will beheldfirinly against longi'tndinalor lateral. nioveinent, the pi'votally connected ears `fand 6 aiding materially in straighteningr the ioints.

It will be obvious that the iiianges 7 are so arranged that when the sections 3 are in their expanded or operative positions the flange of one section will be received in the channel 8 of the companion section, thereby iirinly interlocking the inner edges of the sections and holdingl the saine against lat eral distortion. In this manner strain upon the pivotal connections is relieved and the joints straightened at the points where the inost strain is imparted, it beingr apparent that the channels 'Iorin in eiiect straightenino; ribs for the respective sections.

While the sections 3 are in the positions as shown in Figure 3 and a tire is on the riin it is only necessary to place the toot between the sections above the pivotal con nection V9 and upon exerting,` stress thereon the sections will be forced into lateral alignment with each other and in circular alignment with the rim l, and when the rim is replaced upon a wheel the sections willbe held against accidental collapsing. v

In order to align the '[ianges 7 and chan- The sections 3 have their inner Aedges ornied with vertical flanges 7 and vchaiuiels 8, the outer ends ot said flanges nels 8 itis of course necessary that the ears 5 and 6 of the rim and sections, respeo tively, are disposed in diagonal relation, as are the lugs 4 and slots 10.

What is claimed is:

1. A collapsible rini for automobile tires comprising a transversely divided major rim y section having its ends normally spaced, a

tions being pivotally connected to each other intermediate their ends.

2. A collapsible rim for automobile tires consisting of a transversely divided major rim section having its ends normally spaced, a minor section pivotally connected With each en d of the major rim section and normally in engagement with the opposite ends of said major rim section, each minor scetion having a longitudinal lange and channel, the Ilange of one minor section being adapted to engage the channel of the other minor section to interlock the adjacent sides of said sections. y

3. A collapsible rim for automobile tires comprising a transversely divided major rim section havingl its ends normally spaced, a pair of minor rim sections pivotally connected to the ends of the major rim section and normally in engagement With the opposite ends ot said major rim section, said minor sections having the combined Width of the rim and pivotally connected intermediate their ends to each other, the inner edge of each minor section having aligned flanges and channels, the channel ot one minor section being adapted to engage the flange of the other minor section to hold said sections against lateral displacement.

4. A. collapsible rim for automobile tires comprising a demountable transversely drvided major rim section, minor rim sections pivotally connected to each end oi the major rim section, said minor rim sections being pivotally connected to each other intermediate of their ends and adapted to lie in parallel relation throughout their length lictiveen the spaced ends of the major rim seetion when said minor rim sections are in their active positions.

5. A collapsible rim tor automobile tires comprising a transversely divided major rim section, a pair of minor riin sections pivot ally connected to each other and to the ends of the major riin section, each minor rini section having means on one of its longitudinal edges for interlocking engagement with the similar edge of the companion section, and each of said minor sections normally spanning the space between the ends of said major rim section.
